To all whom it may concern:

Be it known that I, JULIUS WEINBRENNER, a subject of the Emperor of Germany, residing at Thann, Alsace, Germany, have invented a new and useful Method of and Apparatus for Working the Noils from Animal or Vegetable Fibers, of which the following is a specification.

This invention relates to a method and an apparatus by means of which the 110115 or waste which falls from combing machines is carried away directly from the machine to receive further treatment without being subjected again to processes through which it has already passed. The attempts heretofore made in this direction have not yielded satisfactory results as the waste has either been quite unsuitable for further direct working owing to its being recovered in the form ofa loose mass, or, if it has left the combing machine in the form of a fleece, the feeding to the stretching and rolling mechanism and the other devices is carried out without any preliminary treatment of the fleece. Measures which render possible the usual working constitute the subject matter of the present invention.

The essential features of the invention are the following: The carrying off of the fleece-like strips from the squirrel-cage on which they are formed is effected by means of guide plates which are given a half-twist so that they receive the fleece at one end in a vertical plane and deliver it at the other end in a horizontal plane. These plates, which are preferably formed of sheet metal, guide the individual strips to a table provided with mechanically driven rollers, which are rotated at a higher speed than the squirrel-cage, so that between the said cage and the'rollers there is a certain preliminary stretching. By means of the rollers on the table the individual strips are pressed together into a single band which is then either wound up or conducted to a drawing frame and 'by means of the known mechanisms formed into slivers. The difference between feeding direct to a drawing frame in the known manner and in accordance with the present invention is that in-consequence of the preliminary stretching, the stretching, in the drawing frame can be kept within the permissible limits.

I have illustrated one construction of appa ratus for carrying out the aforesaid method 111 the accompanying drawing, in which:

the cards within the housing a by means of a current of air against the squirrel-cage b and that they leave this cage 1) in the form of a fleece or lap. In the drawing a machine with four heads is shown but the suction housing a is only shown on the last head. The fleeces c from the squirrel-cage b are guided by means of suitably bent guide plates 0! on to a table 6 provided with rollers f which are driven from a shaft 9 that runs lengthwise at the rear of and in the same plane as the table by means of pairs of conical gears 72.. The guide plates 03 are mounted on brackets d carried by the table e. The speed of the rollers f is greater than that of the squirrel-cage b. Consequently between the cage b and the rollers f a preliminary stretching takes place and it is possible to work with a thin fleece. The strips of noils are diverted by means of the guide plates d all in the same direction, superposed exactly and pressed together into a single band by means of the rollers f. This band passes to a drawing frame 2' and is then formed in the known manner into slivers. The speed as well as the stretching efiected by the drawing frame can be regulated as desired, likewise the speed of the squirrel-cage b can be varied so that the compressed noils can be made to form a band of any desired weight.

What I claim as my invention and desire to secure by Letters Patent is 1. A method of working the waste or noils resulting from the combing of animal or vegetable fibers in a combing machine provided with a squirrel cage, which consists in stripping said noils from the squirrel cage in fleece-like strips of similar widths, subjecting each individual strip to a preliminary stretching as it is being stripped off the squirrel cage, superposing the stretched strips one on the other and then pressing said strips together to form a single band.

2. The combination with the rotatable squirrel cage of a combing machine, of a table adjacent said squirrel cage, curved guide plates for guiding fleece-like strips from the squirrel cage onto the table in superposed relation, rollers situated to engage said strips as they are superposed one o the other, and means to rotate said rollers at a greater speed than that of the squirrel cage whereby the fleece-like strips are given a preliminary stretching between the squirrel cage and table.

3. The combination with the rotatable squirrel cage of a combing machine, of a table adjacent said squirrel cage, curved guide plates for guiding fleece-like strips from the squirrel cage onto the table in superposed relation, rollers situated to engage said strips as they are superposed one on the other, means to rotate said rollers at a greater speed than that of the squirrel cage whereby the fleece-like strips are given a preliminary stretching between the squirrel cage and table, and a drawing frame situated at the end of the table through which the superposed strips pass.

4. The combination With the rotatable squirrel'cage of a combing machine, of a table situated adjacent said squirrel cage and extending longitudinally thereof, curved guiding plates for guiding fleece-like strips from said squirrel cage onto the table in superposed relation, rollers vsituated adjacent the delivery end of the guide strips and which act on said strips to lay them oneon the other, and means to rotate said rollers at a greater speed than that of the squirrel cage whereby the strips are given a preliminary stretching before they are superposed one on the other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
